Patented Sept. 3, 1918.

Application filed September 6, 1917. Serial No. 190,036.

To all lwhom t may concern:

Be it known that I, MAsUTARo KAmuMI, a subject of the Emperor of Japan,resldmg at 152 9th avenue, Seattle, in the county of King and State ofWashington, have 1nvented certain new and useful Improvements in Shoes;and I do hereby declare the following to be a full, clear, and exactdescrlption of the invention,` such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in shoes, and particularly toshoes with removable and interchangeable heels.

It is an object of the invention to provide heels and shoes soconstructed that when edges of the heels on a shoe have been worn olffrom a side of the heel section that the section may be taken ofi' andchanged to theA opposite shoe, and the worn heel from the otherinterchanged with the first one, thereby securing greater wear from theheels, and also preventing the shoes from running over to the sides.

rlhe invention further provides for the ready and rapid interchange ofheels by the wearer thereof, without any special tools therefor, andprovides for the eiicient locking of the heel when in place.

The invention consists in the construction, the organization and indetails more fully described hereinafter, one embodiment of theinvention being shown in the accompanying drawing in which.

Figure 1 represents a shoe with a heel in place, with the front portionof the shoe turned up, and showing in dotted lines, the normal positionof the shoe;

Fig. 2, represents a front view of the heel section assembled andlockedwith connecting key and pins;

Fig. 3, is a bottom plane of the upper section of the heel.

Like numerals on the several figures represent like parts, the upper ofthe shoe is designated at 1. 2 is the removable section of the heel madein any number of lifts of leather or other suitable material heldtogether with nails or other means as N. An upper section 2 of the heelis securely fixed to a shoe sole 3 by nails N or otherwise, both theupper and lower sections 2 and 2 having longitudlnal keyways in theiropposing faces cut out wider in the bases of such keyways to formholding shoulders 2a and 2*. The keyways shown are of dovetail shape anddo not extend the full length of the heel, so that the heel has theusual appearance. A key 4 made of wood or other suitable material isconstructed with a shape or form to lill the two opposed keyways insections 2 and 2'; and when driven into the keyways from the breast ofthe heel the two sections 2 and 2l are held securely against each other,so that the heel as completed resembles any ordinary shoe heel.

Section 2 carries a plurality of dowel pins 5, 5, and section 2 isprovided with holes 6 into which the pins lit, and these prevent thesections working out of proper alinement. y

The shoe sole 3, in Fig. 1, is turned up leaving clearance space so thatthe key can be inserted into the keyway in 2', as the bottom of thesole, as here shown forms the top of this keyway. When down in line ofnormal position for use, shown in Fig. l by dotted line, pressure may beapplied to the outer front end of the key by the adjacent position ofthe sole and so prevents the key from working loose until the wearerdesires to remove the same, when the sole is turned up and the keyremoved, whereupon the outer section 2 readily drops off or is removedby inserting a blade and lifting the same off of the dowel pins or thekey can be driven in and friction will hold it in place. Any knife bladewill be suiiicient to remove the parts when desired.

The line of wear, common to many people, is shown at W and this wearcauses the shoe to run over. By simply changing the heels at varioustimes the shoes can be maintained in better shape and much additionalwear secured.

What -I claim as new is:

1. A shoe comprising an upper, a slotted heel lift secured thereto, aslotted removable heel section doweled to the lift, and a key slidablyfitting the slots and interlocking said lift and section, said keyhaving recessed sides,

2. A shoe comprising an upper, a dovetuil key nttnchubie thereto, and :iremovable Yheel section secured tothe shoe by `said key und means forholding the section in alinement to the shoe.

3. In combination a shoe, heel sectionshuv ing opposed undercut keywuys,means for uhning said sections, und n key fitting .said ways to securesaid sections together.

4. In combination a shoe, heel sections having opposed dove-tailkeyways, means for :dining said sections, and a double dovetuil key tosecure said sections together, the key friotionnlly fitting between thebottom section and the sole of the shoe.

In testimony whereof uiix my signature.

MASUTARO KAIZUMI.
